Vishnu Tuning finally managed to eek out a 10 second pass in their single turbo E92 335i that they were once touting would be in the 9's. After multiple unsuccessful attempts (with driver errors) from Vishnu owner Shiv Pathak he was able to get a high 10 second slip by raising the boost according to his data log and shifting cleanly. Details are scarce as Vishnu did not provide information on the youtube video upload and there also is no exterior view to show the slip actually correlates to the run shown in the video.

We will give the benefit of the doubt here but with all secrecy and the multiple attempts to get to this point the performance is simply underwhelming for the time and money investment. The car is said to have run 10.8@131. It recently was dyno'd at 627 wheel horsepower by Insideline so these horses are not translating well to the ground. This single turbo offers considerable lag and the top end pull for the sacrifice simply is not there especially compared to existing solutions such as the Rob Beck twin turbo upgrade which offers far greater spool and performance only a few miles per off through the traps but with far greater driveability.

The previous record was 11.10@127.21 with 19 psi of boost on the RB turbos. These turbos are a much more affordable option that also currently is available. Vishnu claims 23.5 psi of boost for this 10.8@131 mph run. Is it worth the minor top end benefit for the estimated $8500+ plus install? We do not think so and considering the way Vishnu hyped this the results are very underwhelming. The low end torque sacrifice is not being justified with a large top end gain.

We wish Vishnu luck in the future but for now this is still an experiment and work in progress that is tough to buy both figuratively and literally. There are more affordable options that work better for daily driven N54 vehicles that offer 97% of the performance in practice (as in not just a dyno queen) with less compromises. Not to mention for users to repeat what Vishnu has done here with their own single turbo it will likely be far more difficult as they will not have the option of risking their engine with higher boost and timing advances simply to try to eek out a tenth to squeeze past what already exists and get into the 10's. It may be a record, but it certainly is not impressive considering where the bar was already set with far less horsepower and much more affordable tuning and hardware options.

+1, I've said it before too, no idea why it's so segregated when it comes to BMW. I use the forum mostly for information vs a social destination so it doesn't affect my ownership of my BWM, but that being said when I see how different it is on some of these GM / Evo / Benz forums I'd be lying if I said it didn't factor into the next project car I buy.

I trust Shiv's logic behind AT transmission, but I dont expect it to last forever at this power level. Depends on how complicated it is, I might just do manual swap if not Level 10 like enrita since he seems to be very happy with the upgrade.

wow welldone @creaminz, the car looks way better. I'm not a fan of any kind of conversions (the M3 front end), so i can't say it looks great but definitely way better than what it used to be. Another right step would be building the transmission.

Just read Sticky's back handed compliment based writ eup on Shiv's 10 second pass....wow! I honestly can't believe the way you handle yourself on here....regardless of it being your site or whatever. Just out of curiosity, because I honestly don't know but am curious, what have you run in your car and what all do you drive?

I believe he drives a supercharged E9x M3.

Sticky hates on n54s in general, but I think Sticky hating on a N54 (when compared or stated to be greater than the S65) and allowing open forum versus banning people who disagree with him is a hell of a lot better way to run a forum.

How about what do you drive and who are you?

Perhaps you should see how Vishnu conducts themselves here first before questioning how I respond to them?

It wasn't a backhanded compliment as there really was no compliment intended whatsoever as I was not impressed. Marginal results thus far barely exceeding what has already been done. If you want to blindly applaud him go ahead but I will put it in context.

Sticky has a supercharged DCT E92 M3 sitting for two years in a shop waiting to be finished.

He should have gotten an N54 in the meantime to have some fun. That would take the bitterness away from him

If I waited around all this time to get a single turbo N54 only to not be able to beat supercharged M3's on stock internals that have been setting records for years now you would see real bitterness at that point.

Ever thought about how it's not only about beating other cars (there will always be someone faster) but ENJOY DRIVING your car, goddamnit. Of course, the faster, the merrier. But even on stock turbos my car puts a smile on my face every day I drive it, especially because it handles like a dream. I wouldn't be so happy if my car was a decorative piece of furniture in some garage...

But over two years, you've had plenty of time to make up all kinds of excuses

Actually what I thought was creating a unique build to promote my forum which is what the endgame is all about. In the meantime the forum has grown considerably. I have other cars to drive in that meantime. It's a project car. I understand for most of you that your 3 Series is your only car so it's a big deal and sacrifice to you. I'm not you and I'll continue to do as I see fit with my things and you do what you want with yours.
